Abstract
A relative motion reduction device is disclosed that reduces the relative motion between two ships mooring in parallel at sea. The disclosed relative motion reduction device is disposed between adjacent fenders among a plurality of collision preventing fenders disposed between two ships to attenuate waves between the two ships. A porous plate is provided, and a plurality of porous plates are supported at both ends thereof connected to adjacent fenders, respectively.
Description
The present invention relates to a device for reducing the relative motion occurring between two ships mooring in parallel at sea by waves and the like.
In general, natural gas is collected at sea and then liquefied to be stored and transported to the consumer in the form of Liquefied Natural Gas (LNG). In the production, storage and transportation of such liquefied natural gas, vessels such as LNG Floating, Production, Storage and Offloading (FPSO) and LNG Shuttle are used.
The LNG stored in the LNG FPSO is unloaded into the LNG Carrier, where the two vessels, the LNG FPSO and the LNG Carrier, are anchored in parallel at sea.
1A and 1B are a plan view and a front view showing two ships mooring in parallel for the unloading of LNG.
Referring together to FIGS. 1A and 1B, two

Embodiments of the present invention provide a relative motion reduction device between two ships that reduces relative motion by damping waves between two ships mooring in parallel at sea.
According to an aspect of the present invention, in the device for reducing the relative motion between two ships mooring in parallel at sea,
A plurality of porous plates arranged between adjacent ones of the plurality of collision preventing fenders disposed between the two vessels to attenuate waves between the two vessels, and connected in a row and having a plurality of through holes, respectively; Equipped,
The plurality of porous plates may be provided with a relative motion reduction device between two vessels, characterized in that both ends thereof are connected to and supported by the adjacent fenders, respectively.
The plurality of porous plates may be connected to each other to be adjacent to each other so as to be folded or unfolded. In this case, the plurality of porous plates may be connected to each other by a connecting plate or hinge having flexibility between adjacent ones.
In addition, both ends of the plurality of porous plates and the adjacent fenders may be connected to each other by hooks and rings.
In addition, a connection member may be coupled to each of both ends of the plurality of porous plates, and the connection members may be connected to the adjacent fenders.
In addition, the connecting member is a relative motion reduction device between the two vessels, characterized in that made of a material that can float on the sea surface.
According to the device for reducing the relative motion between two vessels according to the embodiment of the present invention, since the waves between the two vessels are attenuated by a plurality of porous plates in a line, the relative movement between the two vessels caused by the waves is reduced And additionally leads to a reduction of the mooring load. Accordingly, the loading of cargo between the two ships can be made more stable. And, it can be installed to be floating on the sea surface between the two vessels using a conventional fender, it can be stored separately from the fender when not in use.
